Zero boost leaks, she now holds what is required very nicely

So making good power no doubt, although there is room for improvement as the torque is lower than average. Increasing the boost made more power but only 10lbs/ft more torque, you would expect to see 20-30lbs/ft on a GT3071R. While there could be a number of reasons for this the most likely culprit is the peashooter exhaust causing excessive back pressure. Luke is unsure of the downpipe but I am 99% confident it is only 2.5" (an original H&S downpipe) with a 2.5" exhaust all the way back, too small for Luke's application.
